MEAT-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 420,583, dated February 4, 1890.

Application filed J' une 14, 1889.

serai No. 314,317. No model.)

To all whom it may concern.'

Be it known that I, VILLIAM W. RENKIN, of No. 84 Irwin avenue, Allegheny, Pennsylvania, have invented a new and useful Improvcment in Meat-Choppers, which improvement is fully set-forth in the following specification, reference being had to the accompanying drawings.

Similar letters of reference indicate corresponding parts.

My invention relates to machines for chopping meat by machinery.

In the accompanying drawings, Figure lis a side elevation of a meat-cutting machine constructed in accordance with my invention; and Fig. 2 is a detail view, partly in section, of one of the plungers andapart of the crankshaftb I A A is frame-work.

A A is a sliding frame, being moved up and down by the screws a a. This sliding frame A has fixed to it the ,crank-shaft D at d d and also cross-beamsD and D2,to which are fixed the guide-caps d* and d8.

A2 is a chain belt on the wheels a and a2 to operate the bevel-wheel a3, and thus move the tank or chopping-pan C by means of the cogs a5.

c c c are wheels running on the track c.

DB is a cross-beam at the top of the framework.

d d d are cranks on the shaft D. These cranks operate the knives f,which are fixed to the vertical shaft P2. Each plunger is forked at an intermediate point of its length between the aligned cylindrical parts or ends F2 F3 thereof, and the fork extends upward till near the top', when it enlarges, so as to allow a free movement of the crank d within the same. vThis enlarged fork is provided with a slot f2 in the sides thereof. This slot is made for the purpose of a guide to the upward and downward movement of the plunger P2. i lInside this fork is the pitman P', secured to the crank d and pivoted to the plunger P2 at ft At the top of the fork F is a small shaft passing up through the beam D3. This serves .as a guide to the movement of the stems or shafts PB. t

The several stems or shafts P2 work verti- `C, made so by usage.

cally, operating the knives in the pan C, which is continually revolving on the wheels c c.

Thus constructed my machine will be easily put together or taken apart for repairs. This is done by simply removing the boxing d', d2, and d8. Then the shaft D is passed through the slots f2 of the forks F, which are then put in position.

On the pan C, I place a cap or vcovering A3, preferably made of sheet-iron sloping backward, through which the plungers P2 pass. Theuse of this covering is to prevent substances like oil from falling into the can when the chopping process is going on.

The screws a a are to be used in raising or lowering the knives f to meet the changed condition of the wooden block within the pan The set-screws a4 may be used for the same purpose.

Instead of the crank-shaft D, I can use eccentrics to operate the knives.

Having thus described my inventiomwhat I claim, and desire to secure by Letters Patent,

isd

l. In a meat-chopping machine, the combination, with a rot-ary receptacle carrying a bed and the main supporting-frame, of a vertically-adj ustable frame supported within the main frame and having the upper and lower bars thereof provided with the verticallyaligned guides, the vertical adj listing-screws supported in' the supplemental adjustable frame, thc reciprocating plungers, each having the parts F2 FB thereof fitted in said aligned guides and provided with the forked intermediate part F and the longitudinal slots f2,

a crank-shaft passing through the slots f2 in the plungers and having its cranks operating in the forked parts of the plungers, and the ,pitmein each located in the forked part of one of the plungers and connected to the crankshaft and to the plunger at the base of the forked part thcreof,substantially as described.

2. In a meat-chopping machine, the combination of a main frame, a rotary receptacle carrying a bed and having a circular rack on its bottom, a dri ving-shaft geared to said rack for rotating the receptacle, a crank-shaft connected by an intermediate sprocketchain with said driving-shaft, a main frame, a vertically-adjustable frame supported in said IOO main frame and having its upper and lower In testimony that I claim the foregoing as bars provided with vertically-aligned beim my invention -I hereto set my `hand in pres- Io ings, the vertical adjusting-screws supported ence of two Witnesses.

in the supplemental adjustable frame, the
